Publication Small infrarenal aortic diameter associated with lower-extremity peripheral artery disease in Chinese hypertensive adults
(Nature Publishing Group UK, 2017) Liu, Jie; Jia, Xin; Jia, Senhao; Qin, Xianhui; Zhang, Tao; Liu, Lishun; Li, Haibo; Rong, Dan; Zhou, Ziyi; Song, Yuxiang; Zuo, Shangwei; Duan, Chen; Wu, Zhongyin; Wei, Ren; Ge, Yangyang; Wang, Xian; Kong, Wei; Xu, Xiping; Khalil, Raouf; Huo, Yong; Guo, WeiSeveral studies suggest that infrarenal aortic diameter is associated with lower-extremity peripheral artery disease (LE-PAD). However, data regarding the associations between infrarenal aortic diameter and LE-PAD are limited, especially in large sample populations and Asian or Chinese populations. Our analysis included 17279 Chinese hypertensive adults comprising 6590 men and 10689 women with a mean age of 64.74 ± 7.41 years. Participants were selected from 22693 candidates from two large population-based cohort-studies. The primary noninvasive test for diagnosis of LE-PAD is the ankle–brachial index (ABI) at rest and typically an ABI ≤ 0.90 is used to define LE-PAD. The prevalence of LE-PAD was found to significantly decrease as the aortic diameter increased according to the tertile of the aortic diameter. LE-PAD was significantly more prevalent in the lowest tertile (OR = 1.58, 95% CI = 1.29–1.94, p < 0.001) and similarly prevalent in the highest tertile (OR = 0.92, 95% CI = 0.73–1.16, p = 0.49) when compared with the median tertile. No significant interactions between the aortic diameter and any of the stratified variables were found (all p > 0.05). In conclusion, Small aortic diameter (as opposed to large aortic diameter) is significantly associated with LE-PAD in Chinese hypertensive adults.
